ISL43113IBZ-T

Analog Switches, Multiplexers, Demultiplexers Overview

The ISL43113IBZ-T is a low-voltage, dual supply, single-pole/single-throw (SPST) analog switch manufactured by Renesas Electronics Corporation. It features a Normally Closed (NC) configuration and is housed in an SOT-23 package. The device operates on dual supplies ranging from ±1.5V to ±6V and is fully specified for ±5V and ±3.3V with 10% tolerance. Key electrical parameters include an ON-resistance of 15Ω, ON-resistance flatness of 5Ω, and charge injection of 7pC. Leakage currents are specified at a maximum of 5nA (off) and 20nA (on) at 85°C. Switching times are fast, with tON at 40ns and tOFF at 25ns. The component offers break-before-make operation at ±5V and provides minimum 2000V ESD protection per Method 3015.7.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'T' indicates tape and reel packaging when sourcing this part number. Confirm the manufacturer designation as Renesas Electronics Corporation, noting the historical Intersil lineage. Ensure the component meets RoHS compliance requirements for your assembly process. Check for end-of-life status or obsolescence notices before finalizing procurement plans.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the ISL43113IBZ-T when a Normally Closed (NC) SPST analog switch is required for low-voltage dual-supply designs. This model is appropriate for applications demanding sub-nanoamp leakage currents and fast switching speeds. Consider the SOT-23 package size for board space limitations. Compare against the ISL43112 if a Normally Open (NO) configuration is needed instead.

Analog Switches, Multiplexers, Demultiplexers Part Context

The ISL43113 belongs to the ISL4311x family of precision, high-performance analog switches designed for low-voltage operation. This family includes the ISL43112 (Normally Open) and ISL43113 (Normally Closed). These devices are engineered to offer lower supply and leakage currents compared to other single SPST switches, making them ideal for custom multiplexer applications and next-generation portable electronics.
